DESCRIPTION:

The WHD-6000-S Weld Hole Detection System can provide reliable and fast detection of weld holes in process lines. This sophisticated, state of the art sensor responds in less than 50 µseconds to a light pulse as short as 100 µseconds. The wide field of view allows the sensor to work even with off-center strip.

The sensor is equipped with an ultra fast Silicon photo cell and comes with a compatible infrared light source to ensure detection at distances between three and 10 feet. It also comes with a pointing laser to help in alignment of the sensor and light source.

The WHD-6000 Sensor can operate with any radiant bar emitting in the 750mn to 1000 nm range. The operating range of the strip speed depends on the weld hole size, and typically covers speeds from 0.2m to 20m/sec.

For applications requiring a lower minimum speed, ASC offers a solid-state modulated radiant bar (RB-3000-WHD), which allows fully static operation down to 0m/sec. The radiant bar must be longer than the maximum spread of the weld holes across the strip, and placed under the strip as close as possible to the bottom surface of the strip.

The Weld Hole Sensor generates approximately 40ms long detect output, upon detecting a flash of radiation. The detect output will be terminated after 40ms, even if the source of radiation is still present.

The proper installation and alignment of the WHD-6000-S is crucial for the operating performance. The narrow field-of-view requires precision alignment on the product, and the high sensitivity requires proper adjustment of the threshold and gain to prevent false triggering from background radiation and a wide dynamic range of signal detection.
